SLIDABLE SASH`SUPPORT REPLACEMENT `DEVICE Filed March 22, 1958 2VShsets--Sheec 2 Patented Mar. z8, 1939 PATENT orricE 2,152,361 sLmABLEsAsH silirron'r REPLACEMENT VICE August Ruesch, New York, N. Y.Application Mallh 22, 1938, Serial N0. 197,328 2k claims. (ol. usf-202)This invention relates to slidable sashes as used in connection withwindows in buildings, and more particularly to the iiexible supportswhereby they are held suspended in adjustment for height.

Such supports commonly consist oi cords ork chains connected at one endwithin recesses in the sash sides, passed over pulleys set in the win-.dow frame and attached to weights counterbalancing the sash.

Cords eventually wear out and chains break, endangering the glass in thesash by shock in falling, and further require considerable effort toadjust, as the connection to the counterweight becomes ruptured,rendering it necessary to replace the support.

Such renewal has hitherto necessitated removal of the sash from theframe, requiring the service of an artisan involving expense, delay andtrouble.

It is therefore an object of the invention to provide a simple devicefor replacing a new cord or chain without removal of the sash from thewindow.

A further feature is in the provision of an appliance to be incorporatedin the window sash whereby substitution of its supports is easilyeffected.

These important objects are accomplished by the novel construction andarrangement of parts hereinafter described and illustrated in theaccompanying drawings, constituting a material part of this disclosure,and in which:

Figure 13 is a side View oi a modified form of support anchorage.

Figure 14 is a side View of a still further modi- 5 cation in supportanchorage.

Figure 15 is a transverse sectional view taken on line I5-I5 of Figure16.

Figure 16 is a sectional view, similar to Figure 2, but showing amodified arrangement of parts.

Referring in greater detail to the drawings, the window frame, shown inFigure 1, consists of the usual Vuprights 20 connected at their upperends by a cross-piece 2|.

These uprights are channelled to receive sash 22--23 enclosing thecommon glass pane 24, the window frame being provided with pockets inwinch are sash pulleys 25 over which are trained flexible supportingelements, as the chains 2S or cords, their lower ends being attached topendant weights, not shown.

The upper side elements 22 of the sash have undercut longitudinalrecesses 28 centrally of their width and open, as at 29, at their outersides. 25

The top element 23 is also recessed to receive flat plates 30, held byscrews 3l and have notches 32 in their outer ends.

Disposed in the recesses 28 are bars 33 having which one of the screws3| passes, the flanges being overlaid by the plates 30.

The lower ends of the bars 33 have thickened terminals 35 on their outersides, provided with recesses 36 through which extend pins 31, thesepins adapted to engage the last link in the sash chain 26.

Fixed midway the length of the bars 33 are screw-studs 38 to extend fromtheir rear sides .L0

. andv engage in sockets 39 set in the sash sides 22.

In order to guide the chains, a filler 40 is disposed in each recess 28,these bars having longitudinal recesses 4| in their outer surfaces;claws 42, at the lower ends of the bars 40, straddle the chains, and attheir upper ends are passages 43 for the insertion of a pin or the likewhen maneuvering the chains.

In the modification shown in Figures 12 and 13, the bar 33 is formedwith a flat forward extension 45 at its lower end in which is fixed ascrew-eye 46 to engage the end of a cord 41 in a manner consideredplainly apparent.

The remaining Figures 14,k 15 and 16, show a modified form of screw stud48 engageable in moving the plate 3U to permit releasing the Afillers40, whereupon the bars 33 may be swung out- Wardly to allow removal ofthe old cord or chain and attachment of the support to be substituted.Although the foregoing is descriptive of the preferred embodiment of theinvention, it will be apparent that minor changes may be made in itsconstruction, without departing from the scope of the claims heretoappended.

Having thus described the invention, what is claimed as new and desiredto secure by Letters Patent, is: k

1. In a"device for attaching a counter-weighted exible connection to awindow sash, said sash having an undercut longitudinal groove in theupper portion of its side edge, a bar xed in the sash groove, a dowelset in said bar to engage a corresponding opening in the sash, means atthe bottom of said bar to engage said flexible connection, a ller striphaving a grooved outer face through which said connections pass, andmeans to retain said bar within the groove.

. 2. In a device for attaching a counter-weighted exible connection to awindow sash, said sash having an undercut longitudinal groove in itsedge, a bar disposed in said groove, said bar having an integral,angular pad at its upper end secured to the' upper member of said sash,a dowel set in said bar to engage the sash, means at the bottom of saidbar to engage said flexible connection, a removable filler disposed inthe groove t'o fill the" remaining space therein and having a recessedface for the passage of said flexible' connection, and a plate over theends 20 of said bar and ller fixed on the upper element of said sash.

AUGUST RUESCH.
